Why Do We Sweat? Understanding Perspiration

Sweating is a natural process essential for regulating our body temperature and detoxifying the body. There are various forms of normal and pathological sweating.

Types of Normal Sweating

Thermoregulatory Sweating

Thermoregulatory sweating occurs when the body needs to regulate its temperature, for example during hot weather or after physical exertion.

Emotional Sweating

Emotional sweating is caused by nervous excitement, such as anxiety, stage fright, anger, or shock. This type of sweating mainly affects the palms, armpits, soles of the feet, and forehead.

Gustatory Sweating

Gustatory sweating occurs when the consumption of sour, spicy, or alcoholic foods and drinks stimulates metabolism and heat production.

Pathological Sweating Conditions

Anhidrosis

Anhidrosis is a condition where no sweat secretion occurs and affected individuals do not sweat at all.

Hypohidrosis

Hypohidrosis refers to reduced sweat production, where affected individuals sweat less than normal.

Hyperhidrosis

Hyperhidrosis refers to excessive sweat production that goes beyond necessary heat regulation.

Causes of Heavy Sweating

Excess Weight

Excess weight can lead to increased sweating as the body requires more energy to regulate its temperature.

Pregnancy

During pregnancy, hormonal changes occur that can affect sweating.

Stress

Stress can lead to emotional sweating as the nervous system is activated and stimulates the sweat glands.

Alcohol

Alcohol dilates blood vessels and increases body temperature, which in turn leads to increased sweating.

Menopause

During menopause, hormonal changes occur that can lead to hot flashes and heavy sweating.

Infectious Diseases

Infectious diseases such as flu or tuberculosis can cause fever, which in turn leads to increased sweating.

Hyperthyroidism

An overactive thyroid (hyperthyroidism) can lead to increased sweating.

Why Sweat Smells

The smell of sweat occurs when bacteria on the skin break down sweat. It is primarily the fatty acids and ammonia compounds produced in this process that cause the unpleasant odor.

Changes in Sweat Throughout Life

Childhood

Children generally have a less pronounced body odor than adults.

Puberty

During puberty, hormonal changes occur that increase the activity of sweat glands.

Adulthood

In adulthood, sweat production remains relatively constant.

Elderly

In old age, sweat production may decrease.

Other Factors Affecting Sweat Odor

• Diet: Certain foods can affect sweat odor
• Medications: Some medications can change the smell of sweat
• Diseases: Infectious diseases or metabolic disorders can lead to unpleasant body odors
